SWINGING GATE.

SPECIFICATION forming part of Letters Patent No. 501,813, dated July 18,1893.

Application iiled September 7, 1892. Serial No. 445,233. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE FRITZ VOIGHT, a citizen of the United States,residing at Lower Lake, in the county of Lake and State of California,have invented a new and useful Swinging Gate, of which the following isa specification.

The invention relates to improvements in Swinging gates.

The object of the present invention is to provide a swinging gate whichmay be readily opened and closed by the wheel of a vehicle, and whichwill be positive and reliable in its operation, and which will notaccidentally close after being opened.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings and pointed out in the claims hereto appended.

In the drawings-Figure 1 is a perspective view of a gate constructed inaccordance with this invention. Fig. 2 is a horizontal sectional View.Fig. 3 is a detail perspective view of one of the gearing casings, thecap of the casing being removed to show the gearing. Fig. 4 is a detailperspective view of the cap. Fig. 5 is a detail sectional Viewillustrating the manner of connecting the beveled gear wheel with theoperating shaft.

Like numerals of reference indicate corresponding parts in all thefigures of the drawings.

designates a swinging gate provided at its inner end adjacent to a hingepost 2 with eyes 3 and 4, which receive crank bends 5 and 6 of a pintlerod? arranged in horizontal bearing plates 8 of the hinge post. Theupper crank bend 5 of the pintle rod is shorter than the lower one, andwhen the gate is closed it extends in the direction of a latch post 9,while the lower and longer crank bend 6 eX- tends rearward from the gatein the direction of the hinge post 2. The hinging of the gate is suchthat when the pintle rod 7 is turned, the front end of the gate will belifted, thereby disengaging a latch 10 from a keeper 11 and causing thegate to swing open by its own weight; and a reverse movement of thepintle rod causes the gate to close.

The pintle rod is provided at its lower end with a cross-bar 12 which isrigidly fixed to the pintle rod and forms oppositely disposed arms, andis connected at its endsby rods 13 with oppositely disposed crank bends14 of a u wheel of a vehicle to turn the operating shaft and, by meansof the main shaft partially to rotate the pintle rod. The main shaft isjournaled intermediately in a bearing plate 1S of the hinge post and thecrank bends 14 are `arranged on opposite sides of the post, and are ofsuch length that a half rotation of the main shaft will produce aquarterturn of the pintle rod, and thereby open or close the gate. Theconnecting bars 13 are of the same length and when the gate is eitheropen O r closed the crank bends 14 are horizontally disposed, and arethus on a dead center which will prevent any accidental movement of thegate, and when the parts are in this position the crossbar 12 which iscentrally secured to the lower end of the pintle rod is arranged at anangle to the roadway.

The gearing which connects the operating shaft 16 with the adjacent endof the main shaft consists of a beveled gear wheel 19 mounted on theoperating shaft 16 and disposed in a recess 2O of the bearing casing,and a beveled pinion 21 which is mounted on the end of the main shaftand is one half the size of the beveled gear Wheel 19, whereby onequarter rotation of the operating shaft 16 will produce a half rotationof the main shaft and serve to open or close the gate.

The gearing casing 22 has a cap 23 and is provided with main andoperating shaft bearings 24 and 25 and has the recess 2O which isL-shaped and receives the beveled gear wheel in one arm or branch, andthe pinion in the other. The body of the gearing casingk 22 is providedat one side with a depending triangular extension 26, and in a recesstherein is arranged an arm 27 which has attached to it one end of aspring 28 secured at its other end to the lower end of theextension.This serves to maintain the rectangular bend of the operating shaftnormally in a vertical po- ICO sition, whereby the bend 17 may bereadily depressed by a vehicle wheel to give a quarter revolution to theoperating shaft; and after the rectangular bend 17 has been so depressedit will when released be returned to its vertical position by the spiralspring 28.

The beveled gear Wheel 19 which is mounted on the operating shaft isprovided with a' segmental slot or opening 29 in which is ar'- ranged alug 30 of the operating shaft, and the opening 29 is of sufficientlength to permit the operating shaft to make a quarter turn withoutoperating the beveled gear wheel. When the gate is closed, the slotsl oropenings 29 are so arranged that a movement of the crank or rectangularbend 17 of the operating shaft awayfrom the gate would only move the lugthrough the opening 29 and not actuate the main shaft, but a movementtoward the gate of the rectangular bend 17, which would be occasioned bya vehicle approaching the gate, would actuate the main shaft and openthe gate. This operation which is caused by depressing one of therectangular bends would not effect the other operating shaft, but, wouldleave the same in a vertical position and produce a quarter turn orrevolution of the adjacent beveled gear 19 and change the position ofthe opening 29 with relation to the lug 30,Whereby a vehicle afterpassing through the gate will move the other operating shaft away fromthe gate and produce an operation of the main shaft to close the gate. Y

The gate opens against a short post 31 and the operating shafts arejournaled inl suitable bearings 32 mounted on bases or platforms 33.

The cap 2370i? the gearing casing is provided with a cavity or recess 34which conforms to the configuration of the gearing and the shafts,and-completes the bearings forv the latter, and it is provided at oneside with a depending triangular extension 35 which is arrangedcontiguous to the extension 26 and forms with it an arm of the casing toreceive the spiral spring 28 and the arm 27 of the operating shaft. Thegearing casings are mounted on short posts 36 and are secured thereto bybolts 37 which pass through the posts and the lower ends of thetriangular extensions.

l. The combination of ahinge post provided with bearings, a pintle rodjournaled in the bearings and provided near its ends with oppositelydisposed crank bends, the lower bend being longer than the upper one anddisposed rearwardly, a swinging gate provided with eyes receiving thebends, a cross bar fixed to the pintle rod and forming oppositelydisposed arms, a main shaft provided with oppositely disposed crankbends arranged on opposite sides of the hinge post and disposedhorizontally when the gate is opened or closed, and rods connecting thecrank loops of the shaft with the ends of the cross-bar, substantiallyas described.

2. Thecombination of a hinge post provided with bearings, a pintle rodjournaled in the bearings and provided near its ends with oppositelydisposed crank bends, the lower bend being the longer and disposedrearwardly, a swinging gate provided with eyes receiving the bends, across-bar fixed to the lower end of the pin'tle rod and formingoppositely disposed arms, a main shaft provided with oppositely disposedcrank bends arranged on opposite sides of the hinge post and connectedwith the ends of the cross-bar, operating shafts arranged at rightangles to the 'main shaft and provided with rectangular bends, and thegearing connecting the shafts, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses. Y
